Final answer:
In a series circuit with three 20 ohm resistors connected to a 6V battery, the total resistance is 60 ohms and the current in each resistor is 0.1A.
Step-by-step explanation:
In a series circuit, the total resistance is simply the sum of the individual resistances. In this case, the total resistance would be 20 ohms + 20 ohms + 20 ohms = 60 ohms.
To find the current in each resistor, we can use Ohm's Law: I = V/R. Since the voltage supplied by the battery is 6V and the total resistance is 60 ohms, the current in each resistor would be 6V/60 ohms = 0.1A.
So, the current in each resistor would be 0.1A.
